Despite their inexperience on the main tour, both Harrison and Raonic already look more comfortable in the forecourt than most of the top 20 and their willingness to get there hopefully reverses the recent trend that has seen little but one-dimensional baseliners emerge from the juniors.

The most promising thing is that they aren’t alone. Grigor Dimitrov and Richard Berankis are other young players capable of playing all-court tennis, as is Alexandr Dolgopolov, still a top level rookie despite being 22 years old. Whether this means anything remains to be seen. It’s entirely possible that the aforementioned players will adapt their styles to the prevailing ethos of the tour and gradually ditch the variety from their games.

We’ve seen it happen to the likes of Richard Gasquet, Mario Ancic and Jo-Wilfried Tsonga before them but for the good of tennis let’s hope Harrison and co can maintain their all-court styles. Don’t get me wrong. There is nothing wrong with Djokovic, Del Potro et al. Their style is no less valid than any other but the beauty of tennis lies in variety, unique match-ups and clashes of style.

What do you think of these young stars' style of play? Do you think they will keep playing all-court tennis as they progress in their careers?

I've only seen Harrison, Raonic and Dolgopolev. Dolgo, however, I think is too old to be considered with these guys. Harrison has more of an "all court" game compared to Raonic. With a 150+mph serve, it is tough to list a guy as an all courter. His footwork needs some work as well.

That will be the last victory of Rafa for quite some time.. With his joke mentality and pathetic game, I hope the disgusting player loses every single match next season. He's disgraceful. He should just retire. He's a joke.

Henri Kontinen has a great offensive game but I fear that he might be too injury prone. Injured almost all the time, but when he's playing he's brilliant (won Harrison even when injured late last year in Helsinki).

There's an often misconception to what all-court tennis means. Because nowadays all guys stay behind the baseline, everyone thinks that every player that moves sometimes to the net is an all-court player. Well it's not like that.

All court tennis does not mean baselining + s&v at times. It's much more complex.

Take for example Youzhny. He is the ultimate example of an all court player because he works every inch of that court with his shots aka point construction, and when needed, he steps into the forecourt and finishes the point off. That's all court tennis. Sure that doesn't mean you can't s&v and play droppers every two points and call yourself all-court player but I feel that many people today are misguided into believing that.

Btw Berankis is more of an all-court player than Raonic is. Serve has nothing to do with being an all-court player. He might be one of the most complete big servers we'll have but let's step away a little and not throw every accolades in the book at him. Yes he can volley, but that is not his trademark style, just a trick he has in the bag.

if your forehand is powerful and accurate enough you don't need to come to the net.

Is this your way of justifying Del Potro as an all-court player?...he's not. He's extremely one demential, doesn't even have a good serve. These new up-and-coming players are a refreshing to see, contrasting some of the players that just stand at the baseline and hit big forehands.

As far as your question: "Do you think they will keep playing all-court tennis as they progress in their careers?" , I can only offer my opinion about Berankis as I don't think that I am qualified enough in tennis to make any statements about others that are mentioned.

I think Berankis will keep being an all-court player whether he is willing or not, because he doesn't really have a choice. He doesn't have one very strong weapon but is pretty solid in all aspects of the game (one could make an argument about serve, his serve has really been a problem recently), therefore he often HAS to outsmart his opponent by constructing the point in his favor if he wants to win. I don't see that changing, I think point construction will be an absolute key throughout his career.

I think maybe it's similar with Harrison, but as I said I am no expert
